Time-dependent receiver operating characteristics curves of (a) serum calcium levels (b) Myeloma-Related RI, (c) serum calcium levels(black) Vs Myeloma-Related RI(red). The areas under the ROC curve for the serum calcium level were 0.695, however, the areas under the ROC curve for RI were 0.587, respectively .There was no different (p = 0.225)
